n 5 M` @im @M I travels in a direction from left to right in Fig.. 4, itbeing understood that the upper flight of the conveyor (not shown),travels rearwardly or toward the direction of rota-u tion of the rotor.

The rotor is made up chiefly 'of a central operating shaft 4.ofcylindrical form (see 1 Fig. 2). .Spaced radially from-this shaft arethe circumferentially spacedv rows of teeth 5. The teeth are mountedupon angle bars 6 and each angle bar is in turnmounted upon a crank rodbar 7 loi substantially square crosssection. As shownplamly in Fig. 6,the outer ends of the rods terminate j heads at the ends ofthe rods, Iwould stateV that each head (see Figs. 2 and 4) comprises a disk 12which is yformed at its center with a hub 13 keyed at 14 to the shaft 4.Adjacent Vits periphery, this disk is provided -with bearings 15 toaccommodate the aforesaid journals 7'?. In' addition, it is formed witha peripheral angel and this flange is rotatably mounted lupon arelatively stationary drum indicatedgenerally by the reference character17. This drum is rigidly fastened upon the wagon body.

At this time, I would direct attention to Fig. 7 wherein it will be seenthat the drum is provided on its inner face with an eccentricallydisposed ,channel 18V in which the aforesaid rollers 9 are mounted forrotation. In addition the drum is provided with a central hub 19, aportion of which serves to accommodate a roller bearing 20 for theadjacent end portionof the shaft4. lIt will be noticed that the outerl1end o'this hub is constructed to provide a convex enlargement 21turnable in a bearing 22 of corresponding construction. I` might statehere that the purpose of the bearing constructed by the parts21 and22-is to allowthe drum 17' to be lturned in order'to dispose theeccentric channel 18 at the proper point at ther time of installing thedevice upon the wagon body or manure spreader. The bearing 4becomessubstantially inoperative after the drum ispermanently fastened.

With this arrangement, however, it is ob- ;vious that the membercomprising the disk .12 andthe fiange16 rotates about the periphery ofthe fixed drum.

From the foregoing, itwill be seen that Ihave produced a rotary.lelement provided with a plurality ofrows of raking and dischargin teeth.Y Each row. is rockabl mounte upon the. end head. lItfollowsthat duringthe revolution of the rotor, the teeth j bar 7 and teethV carrying means6 will rotate therewith. In addition, .the disks 12 and flanges 1'6 willrotate about the drums. As

each fixed drum is provided with an eccentric channel and as the crankarms have the rollers located in the channel, 1t is obvious that themanure, moving swiftly to the rear ladjacent the top of the rotor, willbeginto leave the teeth as the lattenmove downwardly" and rotate on thejournals 7a in a direction contrary to the-directionvof rotation of therotor as a whole, so thatwhen the teeth vget around near theibottom ofthe'. wagon body,the travel of the rollers in; the channel willhaveserv'edto actuate the teeth in a mannerntofhave forcibly ejected andAdis-A charged the manure therefrom.

It is believed that by considering| the desc-ription in. connection withthe drawings, persons-familiar with inventions of this class will beable to obtain a clear understanding of the same. Therefore a morelengthy description is thought unnecessary. f
